STORAGE BEFORE USE

Liberty pumps are shipped from the factory ready for installation and use. They should be held in storage if the

pump station is not complete. If storage is necessary, the pump should remain in its shipping container. It should

be stored in a warehouse

or storage shed

that has a clean, dry temperature-stable area where the pump and its

container should be covered to protect it from water, dirt, dust, etc. The ends of the cables - (plugs) must be

protected against moisture.

AT NO TIME SHOULD THE PUMP BE STORED WITHIN AN INCOMPLETE WET PIT. THE PUMP

SHOULD NOT BE PLACED INTO THE PIT UNTIL IT CAN BE FULLY OPERATED.

LONG TERM STORAGE

If it is necessary to store a pump for a long period of time, it should be stored indoors in a clean, dry temperature-

stable environment. The pump should be covered to protect it from dust, dirt and water. The plug end of the

cable must be protected against moisture.

Do not allow the pump to freeze.

Prior to installation, the pump motor should be rotated to ensure the seals and cutters are free spinning.

4. Installed pumps which are idle for long periods of time should be manually operated through the breaker panel

once a month to lubricate the seals. Turn off the breaker, unplug the piggyback switch, and plug the pump

directly into the wall socket. Turn the breaker on for 30 seconds. Turn the breaker off, and then plug the

piggyback switch back in.

PUMP INSTALLATION

THIS PUMP IS NOT TO BE INSTALLED IN LOCATIONS CLASSIFIED AS HAZARDOUS IN

ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE,ANSI/NFPA 70.



Grinder pumps must be installed in a tank that is vented in accordance with local plumbing codes.

Installation should be at a sufficient depth to ensure that all plumbing is below the frost line. If this is not feasible,

remove the check valve and size the basin and/or adjust pump differential to accommodate the additional

backflow volume. Consult the factory for details on how this should be done.

The Omnivore Grinders may be guide rail mounted using Liberty's GR20 guide rail base, or stand-alone. (

See

Figure 3, page 11) They may be installed as a completely packaged simplex (single pump) or duplex (two-pump)

system. Installation of the pump shall be in accordance with state and local codes and performed only by

qualified personnel. Typical installations consist of a guide rail mount in a fiberglass, concrete or polyethylene

tank. This section assumes guide rail installation.

NEVER LIFT THE PUMP BY PULLING ON THE POWER CORD.

USE THE LIFTING CHAIN OR CABLE ONLY

Liberty GR20 Guide Rail systems feature a self-aligning mounting bracket. Using the lifting chain, slip the pump

bracket over the upper guide rail bracket. Lower the pump at an angle down the guide rail into the tank. (

See

Figure 3, page 11)

As the pump nears its final position, the straightening rib squares the pump bracket with the guide bracket ears.

When the pump bracket ears hook the guide bracket ears, the chain will slacken.

Grasp the lifting chain and shake the pump to ensure a good seat with the gasket. The pump is suspended by

the bracket ears. The weight of the pump compresses the gasket against the mating flange of the guide bracket

base.

The lifting chain may be removed from the hoist and hooked near the upper guide rail bracket.
